Answer:
x = π/6, π/2, 5π/6, 3π/2
Step-by-step explanation:
cos x = sin(2x)
Use double angle formula.
cos x = 2 sin x cos x
Move everything to one side and factor.
cos x − 2 sin x cos x = 0
cos x (1 − 2 sin x) = 0
Set each factor to 0 and solve.
cos x = 0
x = π/2, 3π/2
1 − 2 sin x = 0
sin x = 1/2
x = π/6, 5π/6
The total solution is:
x = π/6, π/2, 5π/6, 3π/2
Answer:
8.9-1.4x + (-6.5x) + 3.4x
8.9-1.4x - 6.5x +3.4x
-1.4x - 6.5x = -7.9x
-7.9x+ 3.4x=-4.5x
Answer 8.9 -4.5x

First you are going to remove the parentheses then COMBINE LIKE TERMS
Lastly you just put your equation together .
Answer:
Hey!
The 6th term of your sequence is 23!
Step-by-step explanation:
<u>This is how you get it...</u>
1) T6=3n+5 (the 6th term and the equation...)
2. We now do T6=3(6)+5 (3 x 6 then add 5)
3. In other words... T6=18+5
4. We work it out 18 + 5 = 23
HOPE THIS HELPS!!

Answer: There are 13³/₄ quarts of lemonade.
In decimal form, that is 13.75 quarts.
Step-by-step explanation:
Multiply 7 1/2 times 1 5/6
It may be good to change the mixed numbers to improper fractions:
7¹/₂ becomes 15/2 and 1⁵/₆ becomes 11/6
15/2 × 11/6 = 165/12
Changing that back to a mixed number involves dividing
165÷12 = 13 with a remainder of 9.
Make a fraction of the remainder as the numerator and 12 as the denominator. 9/12.
Then simplify: 9/12 = 3/4
Assemble the mixed number: 13³/₄
<em>Another way is to change the fractions to decimals and calculate:</em>
<em>7.5 × 1.833 = 13.7475. Round to 13.75 and change back to a fraction if required.</em>
